I happened upon some MKV files a few days ago that I wanted to watch on my Apple TV. Normally I would convert these files with Handbrake, but I decided to run them through Permute instead. Dan Moren recently recommended the app on Six Colors and I couldn’t be happier with the results. It has a myriad of presets and a simple drag and drop interface — much easier to use than any of the other video conversion apps out there.
